De Gradibus was an Arabic book published by the Arab physician Al-Kindi (c. 801–873 CE). De gradibus is the Latinized name of the book. An alternative name for the book was Quia Primos.[1]

In De Gradibus, Al-Kindi attempts to apply mathematics to pharmacology by quantifying the strength of drugs. According to Prioreschi, this was the first attempt at serious quantification in medicine.[2] He also developed a system, based on the phases of the Moon, that would allow a doctor to determine in advance the most critical days of a patient's illness.[3] During the Arabic-Latin translation movement of the 12th century, De Gradibus was translated into Latin by Gerard of Cremona.[1] Al-Kindi's mathematical reasoning was complex and hard to follow; Roger Bacon commented that his method of computing the strength of a drug was extremely difficult to use.[2]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
